How do green sea turtles know how to go to the light?

Green sea turtles are believed to use a combination of natural instincts and sensory cues to navigate toward light. Hatchlings are drawn to the brightest horizon, typically the ocean, as they instinctively move away from the darker silhouettes of land. This behavior is crucial for their survival, helping them reach the safety of the sea while avoiding predators. Additionally, they rely on the Earth's magnetic fields and other environmental signals for longer migrations.
